But why male models?

Enough with the Red John episodes! Since the Red John reveal will not come until the end of the series, they need pace themselves, in terms of the Red John plot line. Too much useless information, too many red herrings, too many inconsistencies with the RJ character, etc. just annoys and alienates the viewers. You can only dangle a carrot for so long before the viewers get exhausted and stop caring.   The writers need self-control; limit the Red John episodes to two per season, unless they are actually going to develop the RJ plot line in a meaningful way...not just add more dead ends and false summits.   

it's definitely not Kirkland. he did shake PJ's hand but Lorelei had no knowledge of this because she was in prison at the time so it must be somebody from the past. Lorelei hadn't been in touch with RJ since she got into prison.

it's not haffner because he is too stupid to pull it off.

it's not brett stiles because despite differences PJ likes him and vice versa.

the most likely theories are actually most unlikely..that would be too easy

the idea of PJ's father seems plausible, however why would RJ go to such a great lenghts to make carnival surrounding at the place of killing Lorelei?

at the moment I still have no idea who RJ could be. I was thinking about JJ la roche as he has the ability to hold power over people (hence manipulating by Lorelei's words) but his physique is not that of RJ.

perhaps we get more clues at season 5 finale..

Just something that caught my attention in season5 episode16 is wer lorelei is found red, carnival perhaps? look at the props in the background, she was on her way to kill red john wasn't she? why would she end up in what seems to be a carnival? we all know janes background.

Facts:

- "He is Mar" on the wall. A lower case r is an unfinished n.

- Judge Manchester meets Jane in Season 5 Episode 1. Lorelei reveals that Jane has met him in Season 5 Episode 8.

- The judge was the one who gave Jane custody of Lorelei as a prisoner.

- Seems like he's always in the right place in the right time. Like at the Poker game when he talked to Lisbon. He is too minor of a character to keep bringing back without some value.

- Generally seems like an arrogant, manipulative, smart, deceptive guy. He is the type that knows how to get inside people's heads, like how he got inside Minelli's head with the poker games. Maybe he lost on purpose because he knew Minelli would then send Van Pelt to training for some reason.

- The Manchester United football team are nicknamed Red Devils. The writer of the show, Bruno Heller, was born and raised in the United Kingdom.

I know these are all really broad, but anyone else suggested so far would be way too obvious. What do you guys think?

i think that red john is
Agent Ray Haffner
becouse he in agant in cbi and have access to any place in the bilding and can kill the secrtary of bosco ,he is a member in Visualize and he strong enough to be red john,thats what i think?

After the latest episode I am really sad and upset. Frankly, we don't know anything about Red John, Bruno Heller thinks we are fool, therefore he gives us just a little crumble (they shook hands etc.)

I feel, we won't see the unmask Red John end of this season.

I give up now, when the end of the whole season (6th or 7th) I will watch the rest of unfortunately I have to wait until this happen.

The producer in a trap, I think lot of fun put The Mentalist season at side track because of Red John mystery. He always just promises, promises, like a politician.
